Description
[0001] The present invention relates to an electrical component, in
particular a component for surface mounting, comprising a housing
body, preferably configured as a housing block, comprising a
plurality of contact pins which project from the housing body, at
least in portions, and comprising at least one orientation element
on which, at least in the operating position thereof, the contact
pins rest orientated along a predetermined contact contour, at
least in portions.
[0002] The electrical component may for example be a connector, a
plug connector, a microchip, a capacitor or another component which
comprises at least two contact pins and can be connected to a
carrier, preferably a contact carrier, and soldered, for example
via the contact pins thereof, to the contact surfaces of said
carrier.
[0003] The contact pins are for example mounted on the housing body
of the electrical component, the contact pins being shaped from an
elongated shape into a bent contact shape before or after mounting.
In this case, the contact pins must be orientated along the contact
contour. However, tolerances during mounting and deformation mean
that the contact pins are not arranged entirely precisely along the
contact contour, and deviate more or less from their target
position relative to the contact contour. A deviation of this type
may result in insufficiently contacted contact pins in a fitting
process in which an electrical component is to be mounted on the
contact carrier.
[0004] Electrical components are known which have what are known as
J-lead or gull-wing contact pins, which are formed so as to be
substantially C-shaped or Z-shaped. Components equipped with
contact pins of this type can be fitted and soldered particularly
easily as so-called surface-mounted components (surface-mounted
devices, SMDs).
[0005] A problem with bent contact pins such as J-lead contact pins
is that they are usually made of metal and thus have resilient
properties, as a result of which the contact pins may still deform
resiliently in different ways after shaping. In order to orientate
the contact pins in a predetermined contact contour, components
having housing bodies provided with orientation regions which
orientate the contact pins in the desired contact contour are known
from the prior art, for example from WO 2006/093921 A1 and WO
2006/091961 A1.
[0006] U.S. Pat. No. 5,133,670, U.S. Pat. No. 5,354,207 and U.S.
Pat. No. 6,065,978 also disclose surface-mounted components which
comprise an orientation element arranged directly in or immediately
on the housing body.
[0007] Standard housings cannot be used in the case of the known
electrical components comprising orientation elements which are
formed or arranged on the housing body, since the housing must be
specially adapted for the arrangement of the orientation element.
As a result, the known electrical components cannot be used in a
flexible manner, since the arrangement of the orientation element
is already predetermined by the configuration of the housing
body.
[0008] The object of the present invention is therefore to provide
an electrical component which ensures that the contact pins are
orientated in a predetermined contact contour and the component can
thus be fitted in a reliable manner. At the same time the
electrical component must be simple and cost-effective to produce
and usable in a flexible manner.
[0009] This object is achieved for the electrical component
mentioned at the outset by installing the at least one orientation
element with spacing from the housing body.
[0010] Because the orientation element is installed with spacing
from the housing body, no modifications to the housing body itself
are required, in such a way that standard housing bodies of
electrical components can be used without constructional
modifications being necessary with regard to the installation of
the orientation element. Since in the case of the electrical
component of the present invention there is no limitation, with
respect to the installation of the orientation element, to
modifications to the housing body or spatial restrictions which are
predetermined by the construction of the housing body, it is
possible to use orientation elements configured in virtually any
way which can be produced with a high level of precision and thus
allow extremely precise orientation of the contact pins in the
predetermined contact contour.
[0011] In the component of the present invention, the free ends of
the contact pins, which ends project from the housing body, can
therefore be orientated very precisely along the contact contour.
In this case, the contact contour emulates the region of the
contact carrier on which the contact portions of the electrical
component are connected, for example soldered, to the contact
surface of a contact carrier. The surface of the contact carrier is
often planar, for example in the case of a circuit board, in such a
way that the contact contour corresponds to a contact plane in
which the contact portions of the contact pins, which contact
portions are to be connected to the circuit board, are orientated
in a coplanar manner. Contact pins which are orientated as
precisely as possible along the contact contour ensure good fitting
of the electronic component, since this ensures abutment with the
counter contacts of the contact carrier in such a way that the
contact pins can reliably be soldered to the counter contacts.
[0012] The solution according to the invention can be improved
further by means of various configurations which are each
advantageous per se and can be combined with one another as
desired. These embodiments and the advantages respectively
associated therewith are discussed in the following, the
constructional measures and the effects thereof being described
merely by way of example.
[0013] In a first embodiment, the at least one orientation element
can be installed on at least one arm projecting from the housing
body. The arm can be a separate element which is fastened to the
housing body. Alternatively, the arm can be formed directly on the
housing body or can be installed or formed on an element arranged
on the housing body, for example a fastening means. An arm of this
type makes it possible in a simple manner, irrespective of the
design of the housing body, to install the orientation element with
spacing from the housing body.
[0014] In a further embodiment, at least two arms may be provided
which are bridged by the orientation element. In this way, each of
the two longitudinal ends of the orientation element, for example
an orientation plate, an orientation rod, an orientation shaft or
an orientation rib, can be installed on an arm and the orientation
element thus mounted between the two arms.
[0015] Installing the orientation element on the arm also makes it
possible to provide the electrical component with two or more
orientation elements. Thus, for example, two orientation elements
can be installed on the same arm or the same two arms. As a result,
the contact pins projecting from one side or from different sides
of the component housing are divided into two groups, one of which
is assigned to one of the two orientation elements in each case. In
this way the contact pins of the two groups can be orientated in a
respective contact contour which is predetermined by the
corresponding orientation element. The two contact contours may for
example be orientated so as to be coplanar with one another.
[0016] Alternatively or additionally, a further orientation element
may be installed on another side of the component housing on one
arm or on the same arms. In this way the contact pins of a
component, which has a plurality of sides provided with contact
pins, can be orientated.
[0017] In a further configuration a side plate which is installed
on the housing body can form at least one arm. A side plate of this
type can be styled independently of the housing body and thus in a
flexible manner in any desired form and subsequently fastened, for
example adhesively bonded or clipped, to the housing. In principle,
any desired positive, non-positive or cohesive connection is
possible. In order to arrange orientation elements on different
sides of the housing body, at least two arms may be provided which
project on different sides of the housing body, for example a
plate, such as a solder clip or solder plate, which projects on
both sides beyond the edge of the housing body, can be fastened to
a side wall of the housing body, in such a way that the two regions
projecting beyond the housing body each form an arm on opposite
sides of the housing body.
[0018] During production there is great freedom of design regarding
the orientation and shaping of the arm, which can thus project at
virtually any desired point on the housing body and offers great
flexibility in terms of the possibilities regarding how the
orientation element is orientated relative to the housing body when
installed and in relation to the number of orientation elements to
be installed.
[0019] In a further configuration, the components may comprise at
least one fastening means for mounting the component on a carrier,
preferably on a contact carrier, the at least one orientation
element being installed on the at least one fastening means. The at
least one fastening means may preferably form the at least one
plate. The fastening means of the electrical component are
preferably a separate element, for example in the form of a solder
plate or solder clip which is fastened to the housing body. The
fastening means comprise mounting regions which can be connected to
the contact carrier, for example mounting faces which can be
soldered to the contact carrier. By installing the at least one
orientation element on the fastening means, for example a solder
plate or solder clip, which in the case of a plurality of
electrical components is used anyway for mounting the component on
the contact carrier, a flexible and versatile electrical component
comprising an orientation element for orientating the contact pins
in a predetermined contact contour can be provided by modifying the
fastening means. Fastening means of this type, for example solder
plates or solder clips, which are usually produced as stamped
parts, can easily be produced so as to comprise an arm.
[0020] To stabilise the arm, in particular an arm formed on the
fastening means, the fastening means may comprise mounting regions
which can be connected to the contact carrier, the arm comprising
at least one of the mounting regions. If a solder clip or a solder
plate is used as a fastening means, this generally comprises a
fastening portion in the form of a soldering face which is soldered
to the surface of the contact carrier. This fastening region is
usually located on the housing body. In order also to connect the
arm(s) projecting from the housing body to the contact carrier, the
arm may comprise a further mounting region, for example a further
fastening face, which is orientated so as to be coplanar with the
fastening face arranged on the housing body.
[0021] In a further embodiment, the at least one arm may comprise a
retainer for installing the orientation element. The retainer may
for example be formed from a projection projecting from the arm,
with which projection a region of the orientation element is
brought into engagement. For example, a projection of this type may
be configured in the form of a hook into which the orientation
element is hooked. Alternatively, the retainer could be formed as a
closed sleeve or a sleeve which is open on one side, into which a
portion of the orientation element can be inserted.
[0022] In a further embodiment, the at least one orientation
element can be configured such that it can be transferred from a
mounting position, in which it can be installed on the retainer,
into the operating position, in which it is fastened to the
retainer. This embodiment facilitates the assembly of the component
and ensures that the orientation element is properly fastened to
the retainer, since it is initially arranged in the mounting
position on the retainer before it is brought into the operating
position. At least in the operating position, the orientation
element rests against the contact pins and orientates them in the
contact contour. The at least one orientation element may
preferably be configured such that it can be rotated from the
mounting position into the operating position, as a result of which
the transfer is made possible in a simple and space-saving
manner.
[0023] In a further embodiment, a preferably continuous recess of
the arm can form the retainer. The configuration of the retainer as
a recess of the arm is constructionally particularly simple, since
the arm is preferably formed as a stamped element, for example as a
solder plate. The recess may for example be an end groove or a slot
which ends in an edge region of the arm, into which the orientation
element can be inserted. A possibility for holding the orientation
element in the recess is to exploit the bias of the resilient
contact pins in order to press the orientation element into the
recess.
[0024] In one embodiment, the recess can be configured as a
through-hole. A through-hole can be produced in the arm in a simple
manner without lessening the stability thereof. The orientation
element may be configured such that it can be inserted through the
through-hole, as a result of which a reliable retainer for the
orientation element can be produced in a constructionally simple
manner. By styling the outline of the through-hole in a
corresponding manner, for example in such a way that the outline of
the through-hole is adapted to the insertion profile of the
orientation element, viewed in the insertion direction along the
orientation element, an orientation element configured in virtually
any desired manner can be held in the through-hole. By way of a
through-hole which is adapted to the insertion profile of the
orientation element, it can also be provided that the orientation
element can only be inserted through the through-hole and brought
into the mounting position in a predetermined orientation.
[0025] In order to prevent the orientation element from being
removed or released from the fastening means unintentionally,
according to a further embodiment a securing means may be provided
which secures the orientation element against removal from the
fastening means during transfer from the mounting position into the
operating position. In this way the orientation element is held
captively during the transfer. The securing means can be arranged
on the fastening means and/or on the orientation element or can be
a separate part which prevents the orientation element arranged on
the component from being removed without releasing the securing
mechanism. Possible securing means are for example a split pin, a
bolt, a catch mechanism or a screw fitting.
[0026] In a further embodiment, a securing projection can be formed
as a securing means on the orientation element. Arranging the
securing means on the orientation element has the advantage that it
can thus be ensured that the securing means can only be transferred
into the operating position, in which the orientation means is
secured against removal from the component, when the orientation
element is installed in the desired mounting position on the
component. A securing projection can be produced on the orientation
element in a simple manner. A securing projection can also be
brought into abutment with a face of the fastening means or into
engagement with a specific region of the fastening means by
rotating the orientation element relative to the fastening means
and is thus well adapted for embodiments in which the orientation
element is configured to be rotatable.
[0027] In a further embodiment, the electrical component may
comprise a locking element for fixing the orientation element in
the operating position. By way of a locking means it can be ensured
that the orientation element is rigidly connected to the fastening
means, for example an arm of the fastening means, and thus fixed in
the desired operating position. In one embodiment the locking
element can simultaneously also be the securing means. However, it
is also possible to provide a separate securing means and a
separate locking element, the securing means firstly ensuring that
the orientation element is held captively on the component, while
the locking element then ensures that the orientation element is
fixed in the operating position. Any desired positive, non-positive
or cohesive locking elements may be used, for example keys, screw
connections, mortise joints or press connections. In the case of a
positive connection, it is possible to fix the orientation element
to the component and release it therefrom repeatedly. This can be
achieved for example in that the locking element is formed as a
catch means which for example is arranged on the arm and the
orientation element comprises a counter catch which can be latched
to the catch means. A positive catch mechanism of this type, which
is formed by the catch means of the arm and the corresponding
counter catch of the orientation element, can be produced in a
constructionally simple manner and reliably ensures that the
orientation element is secured in the operating position.
[0028] In a further embodiment, the counter catch may be arranged
on the securing projection. In this way, the locking element is
arranged on the securing means. It can thus be provided that, as
soon as the orientation element is transferred into the operating
position, for example by rotating the orientation element relative
to the fastening means, the securing means is latched and the
orientation element is thus fixed.
[0029] The invention is explained below by way of example by means
of embodiments, with reference to the drawings. The different
features of the embodiments may be combined independently of one
another, as set out previously for the individual advantageous
configurations.

[0039] The individual components, and the functions thereof, of an
electrical component 1 according to the invention for surface
mounting on a contact carrier 14 of a first embodiment will firstly
be described with reference to the exploded view of FIG. 1 and with
regard to FIG. 2 to 5.
[0040] FIG. 1 is an exploded view of the electrical component 1--a
plug connector in the embodiment shown--the electrical component
comprising a housing body 2, a plurality of contact pins 3, two
fastening means 4, solder clips 5 in the embodiment shown and an
orientation element 6. In the first embodiment of FIG. 1 to 5, the
electrical component 1 has contact pins 3 only on one contact side
7. The contact pins 3 can be connected rigidly to the housing body
2 of the electrical component 1. For this purpose the fastening
portions 8 of the contact pins 3 are pressed into fastening
openings 9 of a fastening grid 10 located on the contact side 7 of
the housing body 2. The contact pins 3 fastened in the fastening
openings 9 project from the housing body 1 on the contact side
7.
[0041] A spacer portion 11 which extends at an angle to the
fastening portion 8 is connected to the end of the fastening
portion 8 which faces away from the housing body 2. The contact
portion 12 of the contact pins 3, which contact portion extends at
an angle to the spacer portion 11 and substantially parallel to the
fastening portion 8, is connected to the end of the spacer portion
11 which faces away from the fastening portion 8. In the embodiment
shown, a plurality of contact pins 3 are arranged in the fastening
grid 10, which is formed by two parallel rows of fastening openings
9, in such a way that the contact portions of said contact pins are
orientated roughly along a contact contour K--in the embodiment
shown, a contact area K. The contact pins 3 are formed as what are
known as SMD contacts, which can be fastened to contact surfaces 13
of a contact carrier 14, for example to planar solder contacts of a
circuit board.
[0042] In addition to the fastening grid 10, the housing body 2
comprises a lower face 15 and an upper face 16 which extend
substantially parallel to one another and define a housing interior
17 into which a plug (not shown) can be inserted along an insertion
direction E into the electrical component 1, configured as a plug
connector, according to the embodiment shown in FIG. 1 to 5.
[0043] The component is placed on a carrier 14a, for example the
contact carrier 14, in a mounting direction M and mounted thereon.
When the electrical component 1 is mounted on the carrier 14a or
the contact carrier 14, as shown in FIG. 5 and FIG. 6, the lower
face 15 of the housing body 2 is assigned to the fastening surface
13a or the contact surface 13 of the contact carrier 14.
[0044] As is clear from the side view of FIG. 5, but also from FIG.
1, the housing body 2 of the embodiment shown has a substantially
U-shaped cross-section, in other words the housing body 2 is open
on the sides 18 arranged perpendicular to the insertion direction E
and to the mounting direction M.
[0045] In the embodiment of the electrical component shown, these
open sides 18 are closed by plates 5 serving as fastening means 4.
The plates 5, preferably solder plates, are substantially
rectangular and correspond to the rectangle spanned by the U-shaped
side faces 18 of the housing body 2. The solder plates 5 are
latched to the side faces 18 of the housing body 2 and thus
fastened in such a way that they close the housing body 2
laterally. A plug connector is thus formed as an electrical
component 1, on the connection side 19 on which, opposite the
contact side 7, a connection opening 20 is provided for inserting
the plug connector (not shown) into the interior 17 of the
electrical component 1. For latching the solder plates 5 to the
side faces 18 of the housing body 2, the housing body 2 comprises a
catch projection 21 which projects from the side face 18 thereof in
the region of the fastening grid 10. The upper face 16 and lower
face 15 and the fastening grid 10 are also provided on their side
faces 18 with laterally projecting fastening projections 22 which
project from the side faces 18 as rectangular tongues.
[0046] The solder plates 5, which are generally formed as stamped
parts, comprise fastening openings 23 corresponding to the
fastening projections 22. When the solder plates 5 are mounted, the
fastening projections 22 are positioned in the fastening openings
23, which prevents the solder plate 5 from being displaced along
the side face 18 of the housing body 2.
[0047] In the region assigned to the catch projection 21, the plate
5 comprises a catch tongue 24 which latches to the catch projection
21 in a resiliently deflectable manner when the solder plates 5 are
placed on the side face 18 of the housing body 2. The catch
mechanism 21, 24 formed of the catch projection 21 and the catch
tongue 24 prevents the solder plates 5 from being removed from the
side faces 18 of the housing body 2.
[0048] The component 1 comprising plates 5 fastened to the side
faces 18 is shown in FIG. 2, from which it is clear how the
fastening projections 23 are arranged in the associated fastening
openings 23 and the catch tongue 24 is latched to the catch
projection 21.
[0049] The fastening means 4, the solder plates 5 in the embodiment
shown, comprise mounting regions 25. With reference to FIGS. 4 and
5, the mounting regions 25 project beyond the lower face 15 of the
housing body 2 and thus form mounting rails 26 with which the
electrical component 1 can be mounted, for example adhesively
bonded or soldered, on the carrier 14a or the contact carrier 14
once the component has been properly placed on the contact carrier
13 in the mounting direction M.
[0050] An embodiment of the electrical component comprising an
orientation element 6 installed on the fastening means 4 will be
described in further detail below, in particular with reference to
FIGS. 1 and 2.
[0051] The orientation element 6 of the embodiment shown is
substantially rod-shaped with an oval cross-section which has the
shape of a camshaft or an eccentric. The orientation element is
provided along its longitudinal direction L with an orientation
comb 27 which comprises a plurality of teeth 28 arranged side by
side in the longitudinal direction L and represents the cam or the
eccentric part of the orientation rod 6 or the orientation shaft.
The valleys 29 located between the teeth serve as receptacles and
stops for the contact pins 3 and, in the operating position which
is shown in FIGS. 4 and 5, firstly prevent the contact pins 3 from
being displaced in or counter to the longitudinal direction L and
thus prevent adjacent contact pins 3 from touching one another. In
addition, in the embodiment shown the contact pins 3 rest with
their spacer portions 11 in the operating position against the
valleys 29 of the orientation comb 27 of the orientation element 6,
in such a way that the contact portions 12 of the contact pins 3
are orientated in the predetermined contact contour K by the
orientation element 6. When the orientation element 6 is installed
on the fastening means 4 of the electrical component 1 in the
operating position (see FIG. 5), the fastening comb 27 faces in the
mounting direction M of the housing body 2. When the electrical
component 1 is mounted on the contact carrier 14 (see FIG. 5), the
orientation comb 27 thus faces in the direction of the contact
surface 13 of the contact carrier 14.
[0052] On the ends 30 facing in and counter to the longitudinal
direction L, the orientation element 6 is equipped in each case
with a securing projection 31. As explained in greater detail
below, the securing projection 31 forms a securing means 32 which
secures the orientation element 6 against removal from the
component, in the embodiment shown against removal from the
fastening means 4. As can best be seen in FIG. 3, the profile of
the orientation element 6, viewed in the longitudinal direction L,
is substantially L-shaped, the wing- or oval-shaped securing
projection 31, viewed in the insertion profile, in other words in
the longitudinal direction L, and the eccentric comb 27 of the
rod-shaped orientation element 6 forming limbs which are
substantially perpendicular to one another. In the case of the
insertion profile of the embodiment shown, the limb formed by the
securing projection 31 is the longer of the two limbs compared with
the limb formed by the orientation comb 27.
[0053] The mounting and installation of the orientation element 6
on the fastening means 4 will be described in greater detail below
with particular reference to FIG. 2 to 4.
[0054] In the electrical component 1 according to the invention,
according to the embodiment shown in the figures, the orientation
element 6 is installed on an arm 33 which projects from the housing
body 2 on the contact side 7 in the insertion direction. In the
embodiment shown, the arm 33 is formed on the fastening means 4.
The fastening means 4 is formed as a stamped part, the arm 33 being
directly connected to the plate 5 which forms the side cover of the
housing body 2.
[0055] The arm 33 comprises a retainer 34 for installing the
orientation element 6. In the embodiment shown, the retainer 34 is
formed by a continuous recess 35 in the form of a through-hole 36.
The through-hole 36 is large enough that the orientation element 6
can be inserted, along its longitudinal direction L, through the
through-hole 36.
[0056] The outline of the recess 35 formed as a through-hole 36
substantially corresponds to the L-shaped insertion profile, viewed
in the longitudinal direction L, of the orientation element 6, as
can be seen in FIG. 3. Because the limbs formed by the orientation
comb 27 and the securing projections 31 of the orientation element
6 have different lengths, it is only possible to insert the
orientation element 6 through the through-hole 36 in a particular
orientation along the longitudinal direction L of said orientation
element in order to mount it.
[0057] Since, in the case of the electrical component 1 of the
embodiment shown, two identical fastening means 4 are provided on
the opposite side faces 18, the electrical component 1 in the
embodiment shown consequently has two arms 33 each having a
through-hole 36. The length of the orientation element 6 is
calculated such that the orientation element 6 bridges the two arms
33 and can be held in the two through-openings 36, as can be seen
for example in FIG. 4.
[0058] As long as either the securing projection 31 or oval-shaped
cross-section comprising the orientation comb 27 of the orientation
element 6 is located in one of the two through-openings 36 of the
two arms 33, only a displacement of the orientation element 6 along
its longitudinal direction L into the through-openings 36 is
possible. A rotation of the orientation element 6 about its
longitudinal axis, as a result of which the orientation element 6
is transferred from its mounting position, in which it can be
installed on the retainer 34, in other words can be displaced into
the through-openings 36, into the operating position, in which it
is fixed or installed on the retainer 34, is only possible when the
rotation portion 37 located between the orientation comb 27 and the
securing element 31 is mounted in the through-opening 36. At the
rotation portion 37 the orientation element 6 has a circular
cross-section which substantially corresponds to the articulation
at which the two limbs which are L-shaped in profile meet. The
rotation portion 37 is the short region of the orientation element
6, which region is located between the orientation comb 27 and the
securing wing 31.
[0059] When the orientation element 6 is rotated about its
rotational axis D with rotation regions 37 positioned in the
through-openings 36, the profile is rotated out of its congruence
with the through-openings 36 in such a way that the securing
projections 31 rest against the arm 33 and prevent a displacement
of the orientation element 6 in or counter to the longitudinal
direction L thereof. The same applies to the end portions 38 of the
orientation comb 27, at which portions the orientation comb 27
transitions into the rotation portion 37. In this way the securing
projections secure the orientation element 6 on the fastening means
4 against removal during the transfer from the mounting position
into the operating position.
[0060] On the face which faces towards the orientation comb 27, the
securing projection 31 is provided with a catch means 39, in the
embodiment shown a catch lug 39, which, when the orientation
element 6 is rotated through approximately 90.degree., latches into
a corresponding counter catch 40 and locks the orientation element
6 against rotation on the fastening means 4.
[0061] The counter catch 40 is formed as a catch groove on the arm
33 and is directly connected to the region of the through-opening
36 of the arm 33, which region corresponds to the extension of the
limb of the L-shaped through-hole 36, which limb is assigned to the
orientation comb 27. The counter catch groove 40 is formed by a
catch slot 40 which completely penetrates the face of the arm 33.
This configuration has the advantage that the fastening means 4
comprising the arm 33 in the embodiment shown can be used
independently of the side face 18 on which the fastening means 4 is
arranged. Owing to the configuration as a slot, a counter catch 40
is formed on both sides of the arm 33.
[0062] When the orientation element 6 is rotated along its
rotational axis, in other words when said orientation element is
transferred from the mounting position into the operating position,
the contact pins 3 can be orientated along the contact contour K by
the orientation element 6. Configurations are possible in which the
orientation element 6 is only brought into contact with the contact
pins during the transfer, for example by rotating the orientation
comb 27 towards the contact pins 3 arranged after the orientation
element 6 in the mounting direction M. In this configuration the
contact pins 3 do not yet rest against the orientation element 6 in
the mounting position, but rather only in the operating position.
However, it is also possible for the contact pins 3 already to
touch the orientation element 6 in the mounting position and then
to be orientated in the contact contour K when said orientation
element is transferred into the operating position.
[0063] For mounting the electrical component 1 according to the
invention on the carrier 14a or contact carrier 14, the fastening
means 4 comprises mounting regions, as explained above. In the
embodiment shown, mounting regions 26 are provided which extend on
the side faces 18 and in the region of the lower face of the
housing 2. In addition, the fastening means 4 comprises further
mounting regions 25a which are formed on the arm 33. These further
mounting regions 25a may be configured as mounting tongues 41 which
project from the arm 33 towards the lower face 15 at the level of
the through-opening 36. In the embodiment shown in FIG. 6, the
fastening rails 26, the free ends 42 of the mounting tongues 41
which are arranged on the arm 33, and the contact portions 12 of
the contact pins 4 are located substantially in a contact area K
and can thus be associated with and connected to the contact
surface 13 of the contact carrier 14 when the electrical component
1 is fitted on the contact carrier 13.
[0064] Alternatively, the housing body 2 of the component 1 can be
mounted on a carrier 14a via the mounting rails 26, as shown in
FIG. 5. This carrier 14a may, but need not necessarily be identical
to the contact carrier 14, in other words a circuit board 14, for
example.
[0065] This can best be seen in FIG. 5, which shows an electrical
component 1 mounted on the carrier 14a, the contact portions 12 of
which component are connected to the contact surface 13 of a
contact carrier 14 in an electrically conductive and mechanical
manner, the fastening means 4 which faces the viewer being omitted
in the view of FIG. 5 in such a way that the course of the contact
pins 3, which would otherwise be hidden by this fastening means 4,
can be seen. FIG. 5 shows how the contact pins 3 rest in portions
against the orientation comb 27 of the orientation element 6 with
part of their spacer portion 11 and are orientated in the contact
contour K by the orientation element 6. It also shows how the
fastening regions 8 which face away from the contact contour K are
fixed in the fastening grid 10 and project into the housing
interior 17.
[0066] The contact surface 13, to which the contact portions 12 in
the embodiment shown in FIG. 5 are connected, thus rests against
the edge of the contact carrier 14, in such a way that for reasons
of space it is less feasible to mount the housing body 2 on the
contact carrier 14 in this embodiment. In the embodiment shown in
FIG. 5, the electrical component 1 is connected to the contact
carrier 14 only via the further mounting regions 25a which are
formed on the arm 33. To this end, the mounting tongue 41 extends
through a mounting opening 43 which is provided for this purpose
and is formed in a circuit board 14, which forms the contact
carrier in the embodiment shown. One fixing option consists in
plastically deforming the free end of the mounting tongue 42, which
end projects on the side of the contact carrier 14 opposite the
contact surface 13, and thus fixing the mounting tongue 41 in the
fastening opening 43. Alternatively or additionally, the lower
edges 44 of the arm, which edges face in the mounting direction M
and rest on the contact surface 13 of the contact carrier 14, can
be connected mechanically, for example adhesively bonded or
soldered, to the contact carrier 14.
[0067] FIG. 5A is a sectional view along the line A-A of the
component 1 of FIG. 5. The detail merely shows the electrical
component 1 from the connection side 19 up to the region of the
contact side 7, in which region the fastening portion 8 transitions
into the spacer portion 11 of the contact pins 3.
[0068] As can be seen in FIG. 5A, the free ends of the fastening
portion 8 of the contact pins 3 project into the interior 17 of the
housing body 2. FIG. 5A also shows that the fastening openings 9 in
the fastening grid 10 are widened on the contact side 7 in order to
facilitate insertion of the contact pins 3 into the fastening
openings 9. Finally, FIG. 5A shows clearly that the spacer portions
11' of the upper row of contact pins 3 with respect to the contact
area 14, which row can be seen in the sectional view of FIG. 5A,
extends offset from the spacer portion 11 of the lower row of
contact pins 3. While the spacer portion 11 and the fastening
portion 8 of the lower row of contact pins 3 continue in a
substantially straight line in the insertion direction E, the
contact pins 3 of the upper row have a deflection portion 45 at the
transition from the fastening portion 8 to the spacer portion 11.
In the upper row, although the fastening portion 8 and the spacer
portion 11' thus extend parallel to the insertion direction E, the
spacer portion 11' is offset at right angles to the insertion
direction E via the deflection portion 45 and, viewed in the
mounting direction M, extends between two adjacent fastening
portions 8. In this way the contact pins 3 of the two rows can be
assigned to a single orientation element 6.
[0069] Further embodiments of the component 1 according to the
invention will be described below with reference to FIGS. 6 and 7.
Only the differences from the component of the first embodiment of
FIG. 1 to 5 will be described. The same reference numerals as in
the previous figures are used for parts having a function and/or
construction similar or identical to parts of the previous
embodiment.
[0070] In contrast to the component of FIG. 1 to 4, the components
1 shown in FIGS. 6 and 7 comprise more than one orientation element
6, specifically two orientation elements 6. In contrast to FIG. 5
of the previous embodiment, in FIG. 6 the electrical component 1 is
mounted directly on the contact carrier 14 via the mounting regions
25, 25a of said component, the contact portions 12 of the contact
pins being connected to the contact surface 13. As in FIG. 5, the
fastening means 4 which faces the viewer has been omitted in FIG. 6
in order to show the course of the contact pins 3.
[0071] In the embodiment shown in FIG. 6, the arm 33 of the
fastening means 4 is provided with two through-openings 36 arranged
side by side in addition to counter catch slots 40, in such a way
that two orientation elements 6 can be installed parallel and side
by side on the same arm 33. In the second embodiment of FIG. 6, the
mounting, installation and fixing of the orientation element 6
corresponds to that described above with regard to the first
embodiment of the electrical component 1.
[0072] The component 1 of the embodiment shown in FIG. 6 also
differs from the embodiment shown in FIG. 5 by a four-row
arrangement of the contact pins 3. For this purpose, the fastening
grid 10 is provided with four rows of fastening openings 9. The
contact pins of the lower two rows with respect to the contact
surface 13 are assigned to the orientation element 6 which is
closer to the contact side 7 of the housing body 2. The upper two
rows of contact pins 3 with respect to the contact surface 13 are
assigned to the orientation element 6 which is more remote from the
contact side 7, the assignment of two rows of contact pins 3 to one
orientation element 6 in each case corresponding to the assignment
shown in FIGS. 5 and 5A. In principle, a plurality of rows of
contact pins 3 can thus be assigned to one or more orientation
elements 6. In this case, the orientation elements 6 may be
arranged either in succession in the insertion direction E or one
above the other in the mounting direction M, it being possible for
preferably two, but also a plurality of rows of contact pins 3 to
be assigned to one orientation element 6 in each case.
[0073] FIG. 7 is a side view of a further embodiment of a component
1 according to the invention. FIG. 7 also shows the fastening means
which faces the viewer. In contrast to the previous embodiments,
the embodiment of FIG. 7 comprises a fastening means 4 having two
arms 33, which project on opposite sides of the housing body 2 and
are each formed, in accordance with the type of arm 33 of the first
embodiment of FIG. 1 to 5, with a through-opening 36 for receiving
one orientation element 6 per arm 33 in each case. The embodiment
of FIG. 7 makes it possible for one orientation element or, if
desired, a plurality of orientation elements 6 to be installed on
two opposite sides of the component 1 in a constructionally simple
manner using a fastening means 4.
